back to article NSA spies recorded an entire COUNTRY'S phone calls for a MONTH: Report

The NSA is recording all of the voice calls in one unnamed country and keeping those recordings for 30 days at a time as part of a previously undisclosed rolling wiretap programme, according to leaks recently published in WSJ. Millions of voice "cuts" are extracted for long time storage as part of a system called MYSTIC that's …

Kept sectret from the public, or from the target government ?

It's not clear from that article whether the calls were tapped with or without the target country's support.

Well if its the UK you can be guaranteed our lords and masters just bent over and said "sure... just ram it right on in there".

"....if its the UK....." Don't be silly, the UK is probably waaaay down the list. My bet would be on Pakistan as top choice, followed by Qatar, then Saudi, UAE, North Sudan, North Korea, maybe Cyprus (fave hangout for Russian mafia, arms dealers and exiled Palestinian and Lebanese "freedom fighters"), or even Switzerland (not a NATO partner and full of dodgy bank accounts) before we even get round to any large European countries.

Most likely format...

8k PCM, either raw or as a WAV file or ADPCM (.vox).

These are what are used by computer telephony etc, so will be the most immediately available data.

ADPCM is a bit lossy and introduces white noise. It takes half the space, but recording quality does down.

Re: re Lionel Baden

Every call recording system I've ever worked with have used WAVs, it's highly likely that they will be using off-the-shelf stuff, re-purposed and scaled up, so it is highly likely they'll be using WAV, but no lol.

Re: re Lionel Baden

Well, supposing the country is the UK, a quick Google search fetches up the number of 132 million phone calls made every day here. Suppose they all last for an average of 10 minutes (not everyone can match my mother's phone habits, after all), and it's stored as 8kHz 16-bit PCM (8kHz is what the POTS is designed to carry, being sufficient for human voice) then over 30 days you're collecting 1.32x10^8 x 10 x 60 x 8x10^3 x (16/2) x 30 = 1.52x10^14 bytes required to store it all for 30 days. 152TB. It's not peanuts, exactly, but surely the NSA can manage better than this?

And before someone leaps in, yes, MP3 or Vorbis or whatever could reduce that a bit, but bear in mind that they work by throwing away frequencies that aren't interesting, and you've already thrown away 80% of the audible frequency range by encoding it as 8kHz PCM; you're not going to get the same compression ratios that you managed with your CD collection.

Re: re Lionel Baden

@tom7 RE: 8khz

I had actually thought it would of been a better quality and or possibly compressed into another format. that way if needed to they could analyze background data etc etc

But i suppose that 150TB isn't much at all when your thinking about the volume.

But then add on top of that replication etc etc maybe it does add up quite quickly.

Only for ease of use, plenty will do smaller MP3 and even better, many with do vox files, which are tiny.

So long as they are not capturing DTMF tones, as they wouldn't want to fail any compliance laws would they?

Standard industry models are calls lasting 90-120 seconds. Obviously it varies a bit by country and pricing plan, too (Italians talk a lot IIRC, for example).

Re: re Lionel Baden

I make it out, on the given assumptions as:

132*10^6 calls/day,

600 seconds/call,

8000 samples/second,

2 bytes/sample, and

30 days/month

so 1.32*10^8 * 6*10^2 * 8*10^3 * 2 * 3*10 = 3.8*10^16 bytes, which my calculators assure me is 34,560 TB, rather larger than the 152 TB given, but less than the 152 petabytes that the calculation shown actually gives. Still doable, though, with about 8600x4TB disks.

The unnamed country probably is not the UK. I can think of a number of likely ones, none of them English speaking, European, or American (either North or South).

Phone CODECs are a bit different to the normal (linear) kind.

They use a non linear sampling law (Merkins use a "mu" law, the rest of the world a different one). Basically that compresses 12 bits of dynamic range to 8.

The question is do you have to expand this to linear forms to do analysis or can you keep it in the 8 bit format?

For a worst case calculation, assume everyone in the UK is on the phone say 12 hours a day 365 days.

It's a big number.

But not big enough that the cost will deter the true data fetishist.

Depending on the algorithm used, you can get intelligible speech at a data rate of 1kilo*bit* per second. Examples here: http://www.nine-9s.com/prod_speech_codec_comparisons.htm

Re: @Tom7

Following on to that, obviously you're not going to be doing CSI esque analysis of the audio after it's been degraded that much, but perhaps they view the speech part of the recordings as worth having even without detailed background noise. Important targets could be stored at a higher quality.

Re: re Lionel Baden

"had actually thought it would of been a better quality "

Since the phone signalling itself is 8kHz you can't be doing any better than that.

They would be recording the digital stuff, straight off the T3 connections. They would not be storing analogue.

Better numbers.

Pick a smaller country. People like to do digital experiments on New Zealand : population 5M.

Let's say everyone in NZ spends 5 minutes on the phone a day (10 sounds too much). Sampled at 8khz, 8 bits.

That's 360TB. With half-decent compression -> 100TB.

So uncle sam needed to light up multiple (like FOUR) 100Mb cables between his victim and back home without ANYONE there being a little bit suspicious? That must have cost a fortune.

Seems likely the country has a complicit government to have helped out with the logistics and the financing. Pakistan?

Most certainly is Belgium. The NSA are after the recipe for Stella Artois as every Friday and Saturday night in the UK it turns mild mannered people into hooligans and thugs with no fear.

I realise you're only joking but Stella in the UK is actually produced in the UK and tastes like piss compared to the stuff that is brewed in Leuven, Belgium.

Most likly countries would be some which have a limited infrastructure and which are high on the list of evil countries. Therefore China and UK would be ruled out. How about North Korea, Somalia or Ecuador?

Re: most likly countries

That all depends on your definition of evil as well...

If it's a test they would surely want to test it on a high stress target, so they could spot any flaws.

Further though, if the Washington Post knows the country, what kind of journalism is it when you don't reveal it simply because your nation says so? Perhaps there is no actual story and it's simply a plant in order to make everyone else think the NSA have greater capacities than they really do?
